I am making a music player application on android. My Launcher Activity(MainActivity.java) displays all the songs in a Custom ListView. My app was running perfectly and then I decided to add a SearchView widget in the ToolBar.
Now when I type a query in the SearchView, me Searchable.java activity opens up and after 2-3 sconds the whole screen turns black. The search results are shown for a brief time but the black screen stays there permanently.
If don't use the search option then the application shows no such behavior.
Android: Black Screen appears on the screen when search operation is performed by android SearchView

Your app displaying black screen because you are doing search operations on your main thread , that's why your main thread hanging , check your log monitor you will get error like , too much work on main thread , for overcome this issue you need to perform your search operations on another thread or in background and update your view when search completed , you can use Asynctask for background task .

So i was reading the link and I wanted to ask that since the operation to be performed is Searching, should I place the execute() method call inside onCreateOptionsMenu() method? – Prakhar Singh Jan 20 '17 at 16:08
